I have a CERC/4i on a Dell 750 with two SATA drives. Due to a failing cooling system one of the disks stopped working. This has occurred twice before, so I am fairly confident the disk is not (fatally) damaged. Previously, array rebuilding has been triggered by the following set of afacli commands:

AFA0> disk remove dead_partitions 0
AFA0> controller rescan

However, this time it failed to do the trick. I rebooted the box in the hope that the BIOS interface would have something, but nothing obvious. The current state of the RAID1 set is as follows:

I tried to add 0:01:0 as a spare to the set using container set failover 0 (0,1,0) but this seems to have forced the volume into readonly mode and blocked any attempts to use afacli on the controller. After waiting 10 mins or so, I rebooted. State remained as above.

So no my question is: how do I convince the missing drive to re-join the mirror set?
